Abstract: A gas supply system appropriate for an abdominal cavity and a luminal cavity is provided. The gas supply system reduces a pressure of gas, supplied from a source of gas for supplying gas of a predetermined kind, to a predetermined pressure value upon which gas, whose pressure is reduced, is controllably lowered to a first pressure value appropriate for a body cavity of a first kind of a specimen to allow gas to be supplied to the body cavity of the first kind. In the meantime, gas, supplied from the source of gas, is lowered to a second pressure value appropriate for a body cavity of a second kind of the specimen to allow gas to be supplied to the body cavity of the second kind.

Abstract: There is provided a method of fabricating a semiconductor device, including the steps of (a) forming both a p-well region and an n-well region at a surface of a semiconductor substrate, and (b) forming an n-type epitaxial layer on both the p- and n-well regions so that the n-type epitaxial layer contains impurities therein at a concentration lower than a concentration of impurities contained in the n-well region. For instance, the n-type epitaxial layer is formed by chemical vapor deposition in which a process gas including phosphorus or arsenic compounds therein is used. In accordance with the method, it is possible to optimize threshold voltages of both n-type and p-type transistors in a low-impurity channel transistor at a smaller number of steps. This ensures reduction in fabrication cost and enhancement in a fabrication yield.
